The Best Scottish Shortbread

Ingredients

• 2.5 cups all-purpose flour
• 1 cup butter, at room temperature
• 0.5 cup white sugar
• 1 tablespoon white sugar, or as needed

Steps

1. Gather all ingredients. Preheat the oven to 300 degrees F (150 degrees C).
2. Mix flour, butter, and 1/2 cup sugar in a bowl until well combined and the dough holds together.
3. Press dough into an ungreased 11½x7½-inch jelly roll pan until evenly spread. Prick dough all over with a fork to prevent puffing while it bakes. Sprinkle sugar evenly over the top.
4. Bake in the preheated oven until edges are light golden brown, 20 to 30 minutes.
5. Cut shortbread into large squares or smaller squares, as desired, while still warm. Let cool completely in the pan before removing.
